A spherical nonconducting surface of radius R is uniformly charged in its surface with net charge +Q. Calculate the electric field at a point P which is located at a distance R from the right border of the sphere. Calculate the electric field at a point R/2 at each side of the center of the sphere.

2. Relevant equations

I came up with this.

Let p=Q/V

dq = pdV

V = f(x,y,z) = x^2 + y^2 + z^2 - R = 0

∂V = 2y∂y

and E^{→}_{p}= k_{e}∫^{2R}_{-R}dq/y^2 r^{→}

3. The attempt at a solution

After integration, E^{→}_{p}= 2k_{e}Q(ln2)/R r^{→}

My question is, am I applying the concept of electric field due to a charge distribution in the correct way? I think I might have got it wrong with the dV component... Also, since the topic is Gauss Law, how am I supposed to use the concept of a gaussian surface to calculate electric field?
